SHUTTLE Speccation of Letters Patent.

Patented Dec. 29, 1908.

Applicationledprll 10, 1908. SerialNo. 426,326. v

To all whom it may concern:

Be it known that I, JEAN BAPTISTE DAUDE- LIN, aciti'zen of the United States, residing at Fall R1ver, county of Bristol, and Comi monwealth of Massachusetts, have invented certain new and useful Improvementsv in Shuttles, of which the following is a specilication.

This invention relates to shuttles and particularly to thatv class of shuttles known as automatic or hand-threading. In shuttles of this sort the thread is drawn into the eye through a threading slot and it is desired to' retain the thread within theeye against the tendency exerted by the ballooning effect in the unwinding of the thread from the bobbin to work back through the threading passages, thus leaving the shuttle in an Unthreaded condition. In my former' patent No. 858,443 I described a shuttle of this sort in which the thread was drawn around a bushing located inl the shuttle eye and lodged within the same. In my present invention I contemplate the construction of a somewhat similar' shuttle in which the passages and bushings shall be so relatively constructed and disposed as to ve greater assurance in the 'completeness o the threading and security against any dethreading eifect which may be exerted while the shuttle is running in the loom. hTo this end I have constructed and disposed various passages so combined and correlated as to insure the effect desired in the specication which follows in' which I have set forth an embodiment of my invention as illustrative thereof, and which will be more fully describedv therein. This embodiment is illustrated in the drawings which form a part of said specification, throughout both of' which like' numerals indicate corresponding parts.

In the drawings;l Figure l is a plan view of one end of the shuttle. Fig. 2 a side view of the same. Fig. 3 a longitudinal section along the lines indicated as 3 A3 in Fig. 1. Figs. 4 and 5 are side elevations. Fig. 6 an end view of my bushing removed `from the shuttle. y

1 is a shuttle having a bobbin chamber 2 and a transfer threading eye with which the chamber communicates by a passage 3. This passage' may be omitted if desired and the chamber proper continued -as such.

5 is a threading slot leading into the eye and into the bushing 4 located in said eye through the slot 41 cut from the bottom of y the bushing. The bushing 4 is preferably a i tube open at both'ends and provided with the longitudinal slot 41 extendin throughout substantially its entire length iut terminating just short of its ends, terminating in lateral branches 42 and 43. The slot 42 ex, lends circumferentially and is adapted to be located at the inner end of the threading eye while the slot 43 is disposed about the bus 65 ing preferably in the same direction with the slot 42, the same being in most cases rearwardly of the shuttle and on the opposite side of the bushing from the shuttle point 'at the end in which the eye is located.

44 is a longitudinal slot parallel with the slot 41 but connecting a lateral or circumferential slot 43 with the outer end of the bushing. As will be seen by referring to slightly enlarged at its outer end back tothe inner edge of the slot 43. This exposes the upper edge of the slot 41, which appears partly in elevation and partly indicated by dotted lines in Fig 6. By thus exposing the slot 41., a tool with a lin may be entered to engage said slot 41, so that the bushing may be adjusted.

G is a slot or groove in the side of the through the shuttle body to prevent the dislodgment of the bushing in the eye.

S is a guard pin or deiiecting bar also setin the body of the shuttle and passing through the outer portion of 'the shuttle-eye per- 90 pend'icularly thereto. The slot 44 emerges just behind this bar 8 and is covered thereby so that a thread having once risen through the slots 41, 42, 43, 44 will be held out of contact with'the walls of the bushing 95 and be consequently prevented `from again f entering these slots, and particularly the' Slot 44, and thus prevented from becoming unthreaded.

be as follows: When the thread is drawn down through the slot 5 it will pass under and rise in the slot 42. As the thread is drawn back beneath the yeye it will work u 43 under which it will be again deflected until it emerges through the slot 44 behind the bar 8 which causes it to be lifted clear of the -walls of the bushing. In this position, the

without the possibility of its working back through the threading passages.

Fig. 6, the internal bore of the bushing 4 is 725 bushing adapted to receive a pin 7 driven 85.

The operation of my device will therefore m9 through the slot 41 until it reaches the slot 105 thread will be suitably and evenly delivered Various modifications may obviously be made in the extent and position of the slots and the length of the bushing and in other details of structure, all without departing from the spirit of my invention.

\Vhat I therefore claim and desire to secure by Letters Patent'is:

1. In a shuttle, a bobbin chamber, a transverse threading eye, a bushing in said eye and having a longitudinal slot throughout a part of its length terminating just short of the ends thereof, and a circumferential slot at both ends of said longitudinal slot, the slot at the outer end connecting with a second longitudinal slot out of line with said first named longitudinal slot, and threading slots in said shuttle leading to said bushing slots.

2. In a shuttle, a bobbin chamber, a threading eye, a bushing in said eye and having a longitudinal slot throughout a part of its length terminating just short -of the ends thereof, and a `circumferential slot at both ends of said longitudinal slot, the slot at the outer end connecting with a second longitudinal slot out of line with said first named longitudinal slot and threading slots leading below said bushing and around its inner end to communicate with said bushing slots.

3. In a shuttle, a bobbin chamber, a threading eye, a tubular bushin in said eye open at both ends and having a ongitndinal slot throughout a part of its length-and circumferential slots at its ends,VV one of said circumferential slots connecting with the end of the bushing, and threading slots in said shuttle.

4. A bushing for a self threading shuttle having a longitudinal slot throughout a part of its length and terminating just short of its ends, and a circumferential slot connecting With said longitudinal slot at the innerl and outer end thereof, said slot at the outer end terminating in a passage through to the bushing end.

5. A tubular bushing open at both ends for a self threading shuttle having a longitudinal slot throughout apart of its length but terminating short of its ends in a pair of circumferential slots, that at the outer end connecting With the end of the bushing by a second longitudinal slot sta gered relatively to said first named longitu mal slot, and an enlargement in the opening of the outer end to permit the insertion of a setting tool having an engaging fin for the first named llongitudinal slot.

e. A tubular bushing for a elf threading y shuttle open at both ends and havingalongitudinal slot throughout a part of its length kand circumferential slots at its ends, one of -said circumferential slots connecting' with the end of the bushing.

In testimony whereof, I affix my signature in presence of two Witnesses.
